Guess we could've seen this one coming. In February, 2 Chainz appeared in the video for Fall Out Boy's comeback single “My Songs Know What You Did In The Dark (Light Em Up)" and he followed that up by performing with them at the NBA All-Star Game , so it's no surprise then that the Atlanta rapper is now on the official remix of the track, which premiered via OnSmash.

"There wasn't a lot of weirdness getting into it," Fall Out Boy's Patrick Stump told MTV News working with Tity Boi. "He totally got us, we totally got him. "I think it helps that we're fans," Joe Trohman added. "When the vibe is right, everybody works together without really having to discuss how to work together."
